1. MLRA Region 13 Core Geospatial Data Layers for Soil Survey Management Areas

2. October, 2007 distribution to all MOs Data sets delivered on a 1 Tb hard disk. Original distribution included NED, SSURGO, NHD, and miscellaneous (TeleAtlas) features Distribution in file geodatabase format SSURGO was current as of August, 2007 Elevation derivatives generated Data were extracted for SSO areas Core Geospatial Data Layers

9. Stuff you can and should do with data layers Explore relationships in the database Use them for developing work plans Analyze landscape and landform patterns

10. Stuff you shouldn’t do with core geospatial layers Edit line work Worry about topology Perform joins between survey areas
